Abstract
A skid-mounted device for utilizing Venturi injecting tubes to dehydrate the natural gas of a wellhead comprises a base plate, a filter, a cyclone separator, the Venturi injecting tubes and a buffer tank which are connected in series through a natural gas pipeline, channel steels and a steel plate are welded together to form the square base plate, the four corners of the base plate are provided with four hoisting hooks, the filter, the cyclone separator, the Venturi injecting tubes and the buffer tank are respectively fixed on the base plate, the cyclone separator is provided with a blowdown valve, and the natural gas pipeline is provided with a natural gas inlet, a control ball valve, pressure meters, a relief valve and a natural gas outlet. The skid-mounted device has the advantages that: the skid-mounted device adopts a skid-mounted structure, is integrated with the filtration, dehydration, pressure reduction and pressure regulation of the natural gas of the wellhead, has a compact structure, and is convenient to move; in particular, the skid-mounted device utilizes the pressure reduction and diffusion principle of the Venturi injecting tubes, rather than external supplied energy, to separate the natural gas of the wellhead from water, the processing cost is low, and the skid-mounted device is highly adaptable, and can be conveniently used by users.
Description
(1) technical field
The utility model relates to the dewatering unit of well head Sweet natural gas, particularly a kind of skid-mounted device that utilizes the Venturi injecting tube to carry out the well head gas dehydration.
(2) background technology
The well head gas dehydration generally has following mode: method of cooling, absorption process.The principle of method of cooling dehydration is, the water content of Sweet natural gas reduces with temperature and reduces when pressure is constant, and this method only is applicable to the roughing out of large quantity of moisture, also is well head gas dehydration method commonly used.Absorption process is meant the method for utilizing hygroscopic material such as triglycol or active solid absorbed moisture, and this method is applicable to deviates from the contained most of moisture of unstripped gas in the large-scale natural gas device.The shortcoming of these two kinds of methods is: first method need consume the very big energy; Second method then needs hygroscopic material and also will add thermal reduction, device complexity, consumes energy, processing costs height.
(3) utility model content
The purpose of this utility model is at above-mentioned existing problems, provides a kind of compact construction, processing costs is low, adaptability is strong, the user the is easy to use Venturi injecting tube that utilizes to carry out the skid-mounted device of well head gas dehydration.
The technical solution of the utility model:
A kind of skid-mounted device that utilizes the Venturi injecting tube to carry out the well head gas dehydration, comprise chassis, strainer, cyclonic separator, Venturi injecting tube and surge tank and be connected in series by natural gas line, the square chassis of chassis for making with channel-section steel and steel plate welding, four jiaos of the chassis are provided with four Lift hooks, strainer, cyclonic separator, Venturi injecting tube and surge tank are individually fixed on the chassis, cyclonic separator is provided with wash water valve, and natural gas line is provided with Sweet natural gas import, control ball valve, tensimeter, safety valve and gas outlet.
Working process of the present utility model: at first the well head Sweet natural gas enters strainer, isolate in the Sweet natural gas solid; Utilize the step-down diffusion principle of Venturi injecting tube, make the well head Sweet natural gas reduce temperature, the water content of Sweet natural gas reduces with temperature and reduces, thereby reaches the effect of gas-water separation.
The scope of application of the present utility model is: maximum working pressure 4.0MPa; Gas outlet pressure 1.0-1.5Mpa; Single channel Venturi injecting tube work output 500Nm
3/ h.
The utility model has the advantages that: adopt the skid structure, the filtration, dehydration, decompression, the pressure regulation that integrate the well head Sweet natural gas, compact construction, conveniently moving; Particularly need not provide energy in the external world, but utilize the step-down diffusion principle of Venturi injecting tube to make well head Sweet natural gas gas-water separation, processing costs is low, and adaptability is strong, and the user is easy to use.

(5) embodiment
A kind of skid-mounted device that utilizes the Venturi injecting tube to carry out the well head gas dehydration, comprise chassis 8, strainer 2, cyclonic separator 5, Venturi injecting tube 10 and surge tank 11 also are connected in series by natural gas line 9, the square chassis of chassis 8 for making with channel-section steel and steel plate welding, four jiaos of chassis 8 are provided with four Lift hooks 7, strainer 2, cyclonic separator 5, Venturi injecting tube 10 and surge tank 11 are individually fixed on the chassis 8, cyclonic separator 5 is provided with wash water valve 3, and natural gas line 9 is provided with Sweet natural gas import 1, control ball valve 4, tensimeter 6, safety valve 12 and gas outlet 13.
Among this embodiment, Venturi injecting tube 10 adopts two groups and is parallel on the natural gas line 9, and its inlet diameter is 25mm, nozzle diameter 8.2mm, length 450mm.When intake pressure 4.0MPa, top hole pressure 1.0Mpa, single channel Sweet natural gas work output is 500Nm3/h, detects to show that dehydration rate reaches 98%.
This example structure compactness, non-consumes energy, adaptability are strong, and the user is esy to use, safe and reliable, and is respond well.
